Green lines a pixel width on screen! - Galaxy S 4 Q&A, Help & Troubleshooting

Hi all noob here...
Took delivery of a UK Orange unbranded S4 last week. On Saturday evening a couple of green lines a pixel width apart running from the top to the bottom appeared the left side of the screen. Not right at the side, about 3/4 of a way across. No matter what I did to try and get rid nothing would work.
So I range Orange UK yesterday and they are sending me a replacement for delivery today.
No....the wierd thing is these lines have since disappeared! So do I accept the new replacement (which may be full of Orange bloatware as mine seems unbranded) or do I keep mine in the hope these won't appear again and thus saving me the hassle of getting a new phone back to how I want it...Orange say as long as I tell the courier my phone is now ok I can keep my current one and won't get charged. Or I can change over. My choice.
Could these lines return? Anyone help at all?
Thanks!

if it was me i wouldn't take the risk of having those lines coming back

SPV M3100 screen goes WHITE after pushing red button

Hi there!
First of all, thank you all guys for this wonderful site-system, not only the forum! I've been reading this forum/xda-wiki, etc... for months, thought I never posted cuz I always found the answers to my questions by just searching. Well, this is my issue I didn't find an answer to:
I live in Austria, and because the Hermes is sold here only as the T-Mobile Vario II, which is expensive here, I decided to buy the Hermes over ebay (after learning here that all the HERMES phones all almost the same). I bought the SPV M3100 from Switzerland for only 180€, with S&H + turnover tax (unfortunately I ignored that our neighbors are not in the EU) it came to 230€, still a good catch (pouch, 1GB card and some software included).
Well but I think the customs opened the phone for some reason I don't know; because there are opening marks on the top of the phone (unprofessional) and my display goes white when I press the red button (or the area around, even the right bottom of the display), you can see that on the attached video file. Maybe they tried to check the inside of the phone, and screwed it up. I can't do anything, cuz I through away the shipping package, and they don't accept claims without this package , whatever. Sometimes the LCD is white for about 0.2 seconds sometimes it stays white and I have to push the off-button shortly, and than turn it on again (no soft reset, you know, that "stand-by" thing).
PLUS: The 2 halfs of the phone are moving vertically with 1-2mm if you pull slightly on them (imaging holding a burger in front of you and you pull the upper bun off the lower bun, that's how you could compare my phone, but only for 1-2 mm). The seller swore that he had never had that problem, and he never opened it. He also told me, that I can send the thing back to him, if I want (but come on, I already put myself into the whol unlocking, SuperCID, ROM flashing things etc..., and I hoped that some day I could fix that thing, maybe it's a loose connection).
Could it be, that somebody forgot to put back a screw? Now, what about the display issue? Did anybody ever have or see that problem?
Thanks a lot in advance!!!
greets, Sebi.
PS: Unfortunately I can't attach a .3GP file, so I zipped it.

[Q] How to fix the lines on the screen?

Hi there,
after a six month of usage, one and subsequently another two lines appeared on the bottom of my screen. I don't know if it was due to some pressure (I'm very careful) or fastrefresh app (testing it for a couple of minutes). They are not dead, only inverted (if I have a full black screen, they are white, if I have a full white screen, they are black). See the attached photo (there is also one black spot, but this is pecause a pencil drop). The lines will not dissapear after a restart or full battery drain. Is there any possibility or trick/hack how to erase these lines? Some trick with pressure, electromagnetic field, dissmantle, etc.
I want to fix it by myself, because I am in Czech Republic and got my NST via eBay. I don't want to send it back to USA, because it would be too expensive and I would rather buy a new one in the Czech store.
Thank you very much!
if you restore and reroot nook this problem is resolved likely .

Nexus 7 red screen stains problem

Hello, I've purchased yesterday a Nexus 7 in Chile, outside Google Play because they won't ship to P.O boxes and because it's still not available officially on my country. But i have encountered a problem. Whenever I press too hard on the left side of the screen, some red lines and stains apear in the screen, some big enough to cover half the screen! I'm attaching a picture of what happens when it's charging (I won't turn it on until it finishes because it's the first charge)
I've read in the internet it might be related to a manufacturer problem in the screen. I tried screwing the screws in the back side which reduced the amount and frequency of red stains but it won't disappear. This also happens when I'm holding the screen and pressing the back of the left side.
I have one year warranty and i think i'm going to ask for a new one tomorrow, I just hope they accept it after I tampered with the screws.
It's the new 32gB model.
It's my first tablet and it seems I have to return it :'(

[Q] Black screen of death, then too bright with lines, now normal??

Hello,
I got the Galaxy S4 yesterday morning. Today around 9pm the screen was completely black. I could hear sounds and the buttons would light up but nothing worked. I pulled the battery and sim card as suggested via google search and still nothing. I got home and the screen came back on but it was really super bright with horizontal lines that were slightly shifted in one spot on top of each other. I plugged my usb from the charger into it a few times and eventually got a battery charging logo to come up. Had to do that a few more times before I got the screen back up. Now the screen appears normal but I'm scared that something happened to it. Either the screen is going to die soon or maybe it somehow over heated and that is why the screen was acting wierd. I just hope that since it seems normal now that I can get it replaced in store even though I can't duplicate the symptoms.
I'm curious as to what your take is on what's wrong with my phone? It had at least 75% charge before it started acting crazy. I don't want to keep it thinking it's fine and then after 15 days it goes out again and I'm stuck waiting for a repair to be shipped back to me.
Thanks
I just did a live chat with a Samsung Tech guy. He says it's because I installed an app or had a sd card inserted. He told me to uninstall Facebook and any ebook reading Apps and see if that fixes the problem. Do they think people fall for this? So incredible stupid if that's how they train their techs.
I was able to replicate the symptoms again. I bought the s view cover and when installing it had to press a little hard on the edges to snap into place. The screen went black again and did the same thing. Plugging to power then restarting fixed it. I found out that when I press the top right corner around where the time is, the screen flickers black and looks like I wants to cut out. Is there a sensor or digitizer located at that spot. If it's an issue when putting on a case, I see this is going to not bode well for the life of this phone. I went back to the dealer today and she gave me the number and location of a local samsung repair center. I'll have to give them a call tomorrow I suppose. Just be careful of any pressure being applied to the screen, even though mine has been acting up on it's own.
Just checked it now and it went totally black again and is not coming on. I've only had it a few days so not even enough time to load much stuff on it or customize it. I'm with Wind Mobile in Canada. It's getting boxed up and taken to the store asap tomorrow.

G900A Black screen (sometimes)

Hi, the problem started a few weeks ago, when i low down the brightness the screen starts to flicker and it turns to a green/yellowish color, a few days after i woke up and turned my phone but it was black (i leave the phone charging every night before go to bed) when i turn it on by power or home button i just see a few horizontal lines in the upper part of the screen, but it wont turn on, so i got to remove the battery wait a while, then put it back and turn it on again, the screen still black for a while (i cannot see anymore the S5 logo) leave it for a moment, then after few pushes (well a lot actually) to the power button it turns on again and works just fine for the whole day, I've change the android last year to 6.0.1 with odin (I'm not from usa), and changed the battery a couple of months ago, what could it be the problem? battery? dying screen?

I had a similar problem with my S5 a while ago.
The screen used to have these so-called snowstorms and kept glitching and freezing. When I turned the screen off and on again it would stay black, then the phone would reboot and I would have that snowstorm again.
I then replaced the screen and after doing so the phone worked flawlessly (hurrah!) for about 3 months (damn). Then it started acting up again (sh**).
I was really disappointed. What a waste of money. What a waste of time.
Then I thought about the motherboard - that had to be the cause I thought.
So then I replaced that. This was about 2 weeks ago.
Ever since my S5 has been chugging along nicely.
So yeah, in the end it could be the following things causing the problem:
-loose screen ribbon connector
-faulty screen
-faulty motherboard
The S5's screen (flickering) is a commonly found problem.
If you want to spend your hard-earned money on a five-year-old phone like I did then here's more details:
The screen is fairly easy to replace. If you want to replace the motherboard you have to disassemble the entire phone. It shouldn't be difficult after you've removed the screen without breaking it.
I managed not to do so. Here's a video of the tear down process which should help you (quite a lot): https://www.youtube.com/watch?v=fZ_rMo-AdKE&t=191s
If I were you I'd try replacing the motherboard first as it's cheaper. Don't make the mistake of doing it the other way round like I did.
Just search for the model number you want. SM-G900F (Europe and America) has the best support here on XDA and is the most common model.
I wouldn't order a G900A because as far as I know the bootloader is locked down because US carriers don't like us. And I don't think there's an exploit either.
If you want to buy a new screen then make sure you get a genuine one, follow the link or search "S5 digitizer" on eBay: https://bit.ly/2Hww3Dp
The seller I bought the screen from (from China, shipped from Netherlands) isn't selling it anymore so I cannot guarantee any genuineness or functionality. Seller looks reputable though and the pics and description look good and it ships to Europe.
Again, the screen is very expensive, even for an old phone like this! I would try replacing the motherboard first.
Any cheap screens (under 50) you find will most likely be of bad quality. You should not buy them.

Thanks for your reply, i think it will be better to get a new phone then, where i live (f**** argentina) the screen cost more than what i paid for the phone (used but just a few months after release) more than 100 dollars, thanks again.
